What is the cell doing in the G₀ stage?

• The cell is in a resting state and not actively preparing to divide.

• The cell is actively dividing.

• The cell is undergoing DNA replication.

• The cell is preparing for mitosis.

What is a checkpoint?

• A point in the cell cycle where the cell checks for errors before proceeding

• A location in the cell where DNA is stored

• A type of protein that helps in cell division

• A phase of the cell cycle where the cell grows

What happens in checkpoint G₁? pick 2

• checks if the cell is growing well

• checks to see if DNA was replicated correctly

• does the cell have everything it needs to continue

• check to see if DNA is damaged
